In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

|---|---|---|

sensor | Sensor (temperature) |
What people report
Rehlko/Kohler generators work via the cloud; available sensors depend on the generator's instrumentation.
